I use it for over a year. I needed some quality back for my synths. I'm not disappointed. In addition, I have a little amplification (the sound is not bad at all) to help me when I do not want to tire myself out.
The power is not negligible even though I was expecting more given features. I have other models (Solton ...) but I prefer the clarity of Yamaha.
I especially like its small footprint and integrated mixing.
I do not regret this purchase at all.
